Chronic Ulcerative Paradental Stomatitis (Chronic Ulcerative Gingivitis) in Dogs

Occurrence: common
Location of illness: Head/Neck

Chronic ulcerative paradental stomatitis (CUPS) is a painful inflammatory condition of the oral cavity in dogs, characterized by chronic ulcers and inflammation of the gums, lips, and oral mucosa. It is often associated with an overreaction of the immune system to plaque.

The most important facts at a glance

Chronic ulcerative paradental stomatitis (CUPS) in dogs is an inflammatory condition of the oral cavity in which the immune system overreacts to the bacteria in plaque. The exact cause of this reaction is unclear, but genetic factors may play a role, as certain breeds such as Cocker Spaniels are more susceptible. Symptoms include gingivitis, painful ulcers in the mouth, increased salivation, and bad breath. Diagnosis requires a thorough clinical examination, dental cleanings, and possibly biopsies to rule out other conditions. Treatment aims to relieve symptoms and control Inflammatory conditions, often through dental cleaning, antibiotics, and anti-inflammatory drugs. In severe cases, Tooth loss may be necessary. The prognosis depends on the treatment, and regular dental care and veterinary check-ups are crucial for prevention. Research focuses on genetic predispositions, the oral microbiome, and the development of new therapies to provide less invasive treatment options and improve the quality of life of affected dogs.

Causes

A dog’s oral cavity is home to a variety of bacteria that normally exist in a healthy balance. However, in CUPS, the dog’s immune system appears to be overreacting to the presence of these bacteria. The exact cause of this overreaction of the immune system is not yet fully understood, but genetic factors are suspected to play a role.

Some dog breeds appear to be more susceptible to CUPS, including Cocker Spaniels, Cavalier King Charles Spaniels, and other smaller breeds. This suggests that certain genetic predispositions may increase the risk. It is believed that the immune system of these dogs is more sensitive to the bacteria in plaque, leading to a chronic inflammatory response.

The inflammation that occurs in CUPS is the result of an immune-mediated reaction to plaque and Tartar (calculus). These substances consist of bacteria and their metabolic products that accumulate on the teeth. In dogs with CUPS, the immune system appears to recognize these substances as a threat and triggers an inflammatory response to combat them. However, this reaction can be excessively strong and lead to the painful ulcers that are characteristic of the disease.

Other possible causes that have been linked to the development of CUPS include systemic diseases such as diabetes mellitus or autoimmune diseases, which affect the immune system as a whole and may increase the dog’s susceptibility to Inflammatory conditions.

Symptoms

Rare symptoms:

Scarring of Tongue Margins

The symptoms of CUPS are often very noticeable and painful for the affected dog. One of the most common symptoms is bad breath (halitosis), which is caused by the bacterial infection and the breakdown of tissue. This bad breath is often very intense and unpleasant.

Another noticeable symptom is excessive drooling, which is caused by the Pain and Inflammatory conditions in the mouth. Dogs with CUPS may also show difficulty eating, as the Pain makes chewing and swallowing difficult. This can lead to a reduced appetite and Weight loss.

Red, inflamed, and ulcerated areas are often seen in the mouth of the affected dog, especially on the gum margins and oral mucosa. These ulcers can bleed and are extremely painful when touched.

Other symptoms may include Restlessness, Irritability, and a general deterioration in the dog’s well-being, as the constant source of Pain causes significant stress.

Diagnosis

The diagnosis of CUPS usually begins with a thorough clinical examination of the dog by a veterinarian. Particular attention is paid to the condition of the oral cavity in order to identify the characteristic ulcers and Inflammatory conditions. A complete dental examination in combination with a dental cleaning is often necessary to assess the condition of the teeth and remove plaque and Tartar (calculus).

In addition to visual inspection, the veterinarian may take samples of the affected mucous membrane to rule out other possible causes of the symptoms, such as bacterial or viral infections, tumors, or systemic diseases. Blood tests can also be performed to check for the presence of systemic diseases that may be contributing to CUPS.

In some cases, a biopsy of the oral mucosa may be necessary to make a definitive diagnosis. Histopathological examination of the tissue can help identify the characteristic inflammatory changes associated with CUPS.

Therapy

The treatment of CUPS requires a multi-stage approach that aims to relieve symptoms and control the underlying inflammation. One of the first measures is thorough cleaning of the teeth to remove plaque and Tartar (calculus), as these are the main triggers of the inflammatory response.

Antibiotics may be prescribed to combat secondary bacterial infections that often occur with CUPS. In addition, anti-inflammatory drugs, such as corticosteroids, can be used to reduce the inflammatory response and relieve Pain.

In severe cases, it may be necessary to extract some or all of the dog’s teeth to drastically reduce the bacterial load in the oral cavity and control the inflammation. This radical measure can often bring about a significant improvement in symptoms.

In addition to veterinary treatment, special diets and oral care products can be used to support dental health and minimize plaque formation.

Prognosis and follow-up care

The prognosis for dogs with CUPS varies depending on the severity of the disease and the effectiveness of the treatment. In many cases, the disease can be successfully controlled if diagnosed early and treatment is carried out consistently.

Dogs that require Tooth loss often show a dramatic improvement in quality of life as the source of Pain is removed and the inflammation subsides. However, removing many teeth can affect food intake, requiring dietary adjustments.

Because CUPS is a chronic disease, lifelong monitoring and care are required to prevent relapses and ensure the dog’s well-being.

Prevention

The most important measure for preventing CUPS is consistent dental hygiene. Regular brushing and the use of special oral care products can help prevent the accumulation of plaque and Tartar (calculus), which are the main triggers of the disease.

Regular veterinary check-ups and professional dental cleanings are also important to monitor the condition of the teeth and gums and to intervene early if signs of Inflammatory conditions or other problems appear.

For dogs with a genetic predisposition to CUPS, it may be helpful to consider special dietary measures that promote oral health and support the immune response.

Outlook on current research

Chronic ulcerative paradental stomatitis (CUPS) in dogs is a complex and challenging disease that is still the subject of intensive research. Scientists and veterinarians are working to better understand the exact causes and mechanisms of this inflammatory disease. Currently, CUPS is believed to be an overreaction of the immune system to the normal bacterial flora in the dog’s mouth. Current research focuses include investigating the genetic predisposition that may make some dog breeds more susceptible to this disease.

Another area of research focuses on the role of the microbiome in the oral cavity. Scientists are investigating how the balance of bacteria in the mouth can affect the occurrence and severity of CUPS. This research could provide new approaches to preventive treatment or to alleviate symptoms by specifically altering the microbiome.

In addition, the development of new therapies is being explored. While removing the affected teeth is often the most effective treatment method, researchers are looking for less invasive alternatives. These include immunomodulators that are designed to regulate the response of the immune system, as well as new anti-inflammatory drugs. These could help improve the quality of life of affected dogs without the need for extensive Tooth loss.

There are also studies looking at nutrition and its impact on CUPS. Researchers are investigating whether certain diets can reduce inflammation or whether dietary supplements are beneficial. These studies are still in an early stage, but could provide valuable insights in the long term.

Collaboration between veterinarians, dentists, and immunologists is crucial to fully understand the mechanisms of CUPS and develop better treatment strategies. By sharing knowledge and applying the latest scientific methods, researchers hope to sustainably improve the quality of life of dogs with CUPS.
